Description
Technical field
The utility model belongs to field of metallurgical equipment, particularly the rotary spray gun of the belt stirrer used of low capacity hot metal ladle (jar) desulfurization.
Background technology
In existing ironmaking technology, desulfurizing iron is a kind of widespread use metallurgical technology.Present sulfur removal technology is progressively to develop into the desulfurization of torpedo jar, hot metal ladle (jar) desulfurization by the trough desulfurization; Wherein sweetening agent by soda, calcium carbide powder, lime, develop into pure magnesium, sweetening agent adds mode and develops into the spray gun winding-up by artificial, chute, paddling process and blowing process two big technologies have finally been formed, but for China is under the situation of low capacity hot metal ladle (jar) with blast furnace generally, the independent use of above-mentioned two big technologies all can not be satisfied the requirement of desulfurizing iron, and reason is to have when adopting stirring desulphurization that hot metal temperature drop is big, iron loss big, the shortcoming of sweetening effectiveness difference; When adopting pure magnesium blowing desulfurization, then there is the low problem of magnesium utilization efficiency, also do not have better method to solve at present.And traditional blowing device the time is fixed in winding-up, carrying sweetening agent from the air-flow of spout ejection, and the air-flow of ejection produces bubble floating, the reaction of Salmon-Saxl in the process of come-up in sweetening agent and the molten iron.Because ejection tolerance alters a great deal, bubble volume is bigger than normal and unstable, when causing desulfurization splash serious, influence the utilization ratio of the stable and sweetening agent of liquid level.
The utility model content
The purpose of this utility model is to provide a kind of low capacity hot metal ladle (jar) reasonable in design that desulfurization is used simple, easy to operate, and sweetening effectiveness is good simultaneously, sorbent utilization is high, the rotary spray gun of the belt stirrer of long service life.
At above-mentioned purpose, principle of work of the present utility model is to adopt high temperature steel to make rotary spray gun material and belt stirrer, as the proprietary equipment of low capacity iron ladle, hot metal ladle stirring and blowing desulfurization technology.The stirring action of this equipment utilization rotary spray gun is realized paddling process and blowing process combination desulfurization, and sweetening agent adds from hot metal ladle (jar) top when the paddling process desulfurization, and this moment is the blowing desulfurization pulvis simultaneously.When pure magnesium blowing desulfurization, utilize stirring action to smash the magnesium steam bubble and prolong the residence time of magnesium in iron liquid, significantly improved like this magnesium reaction efficiency, reduced the consumption of magnesium.When winding-up magnesium grain, adopt the concentrated phase conveying technology, increased the dividing potential drop of magnesium, improved the solubleness of magnesium, desulphurization reaction efficient is further improved.This rotary spray gun design has special swivel joint, joint flange and agitator, and rifle body and function refractory materials parcel has the speed control by frequency variation function, and the rifle body can be regulated according to processing requirement and insert liquid depth in addition.
Compare with traditional sweetener, this device has increased swivel joint and rotating driving device.The rifle body can rotate on request in the winding-up process.The medium that traditional swivel joint is suitable for is gas and liquid, and this device delivery medium is the gas of mixed sweetening agent.The situation of obstruction can take place in the use.Compare with common swivel joint, this installs employed swivel joint, and to have a service requirements low, good seal performance, and simple in structure, it is convenient to change, characteristic of strong applicability.The sealing material heatproof height of this joint, anti-dust ability is strong, is applicable to various rugged environments.Adopt unified interface during joint design, last termination rapid-acting coupling, the convenient and flexible pipe that dusts joins; Unified flange-interface is adopted in the lower end, but the various rifle bodies of adapted are to adapt to various user mode.
According to above-mentioned purpose and principle of work, the concrete solution of the utility model is:
This rotary spray gun is by the flexible pipe that dusts, swivel joint, suspension system, rotating driving device, spray gun rifle body, joint flange and agitator are formed, the flexible pipe that wherein dusts is connected with the top of swivel joint, the lower end of swivel joint is connected with spray gun rifle body by joint flange, the middle and upper part of spray gun rifle body is equipped with suspension system and rotating driving device successively, and the bottom of spray gun rifle body is provided with agitator.In addition, agitator is four shapes of cross.
It is simple, easy to operate that the utility model compared with prior art has reasonable in design, has simultaneously that sweetening effectiveness is good, sorbent utilization is high, the advantage of long service life.This rotary spray gun design has special swivel joint, joint flange and agitator, and rifle body and function refractory materials parcel has the speed control by frequency variation function, and the rifle body can be regulated according to processing requirement and insert liquid depth, reaches work-ing life more than 200 times.The utility model designs at low capacity hot metal ladle (jar) especially, compares with common winding-up rifle, and the utilization ratio of magnesium grain can improve more than 30%, and can realize the combination sulfur removal technology of paddling process and blowing process neatly.
